That's interesting. What purpose could be achieved by embedding a
PDF inside another like this? What is a standard PDF viewer supposed
to do with the file - simply display the embedded file or display
something else? Is it likely that this has been done intentionally to
discourage using anything other than Adobe Reader (or at least one
obeying a newer standard)?
